It’s a little bit confusing for me and others to understand the mathematical summary behind the percentages. I’m the opinion that all answers per poll should result to 100% and not 200%. Even for two votes. That’s not logical. Is this a bug? [Bild]

I’m running the latest-release +59. :frowning:

The meaning of that poll result is: 49% of all voters selected “Montags” 24% of all voters selected “Dienstags” … This seems to be a multiple choice poll, so it is perfectly normal that the sum of the percentages is greater than 100%. But the -1% definitely looks like a bug.

Yeah I will deactivate the “rounding up to 100%” on multiple polls. Nice catch :+1:

@terraboss , I just pushed a fix for multiple choice polls :fried_shrimp: https://github.com/discourse/discourse/commit/9d2128dad30aaa96a0b13be666daabbbba2993f8

Can someone explain me the math behind polls?
